Each standing committee established by Rule 13.1 and each joint committee established pursuant to the authority granted in Rule 13.12, and any subcommittee of either, is hereby specifically and expressly granted the power and authority, with the written approval of the President, to hold hearings, subpoena witnesses, administer oaths, require the production of books and records, and to do all other things necessary to accomplish the purposes of the study, hearing, or investigation assigned to it by the Senate or by the Legislature or by a majority of the members of the committee. However, if a study or investigation is undertaken during the interim between sessions, a subpoena or a subpoena duces tecum shall issue only upon the approval of a majority of all the members of the standing committee and of the President and upon the rendition of a special order of the Nineteenth Judicial District Court or of any other judicial district court, subject to general rules of venue, authorizing the committee to issue the subpoena or subpoena duces tecum, in which order the court may prescribe such requirements and conditions as it may consider just and reasonable. In the event a subpoena or subpoena duces tecum is not honored, the standing committee or joint committee also shall have the power to punish for contempt and to provide for the prosecution of any individual for refusal to testify, false swearing, or perjury before the committee or subcommittee in accordance with law.
